IMPROVEMENT IN GUIDES FOR WORKING BUTTON-HOLES.

Specification forming part of Letters Patent No. 15,872, dated October14, 1856.

T0 aZZ whom, it may concern:

Be it known that I, OTIS AVERY, of the town of Bethany, county ofWVayne, State of Pennsylvania, have invented a new and use fulInstrument to be used in the Oonstrnction of Button-Holes; and I declarethat the follow clasp is placed at. a proper distance from the side ofthe button-hole, andserves as a guide for the depth of the stitch whichis taken by hand with a'common needle. On the face or working side ofthe clasp is a sliding plate which carries a revolvingtweezers ornippers. This plate traverses on the clasp on a line with thebutton-hole. The tweezers move transversely to the movement of thesliding plate, and are capable of being slid or extended out over theedge of the clasp to catch the thread, and on drawing them back theirrotary motion gives the thread the proper loop to make the button-holestitch.

. To enable others to make and use my inventweezers, which may be madeof any elastic substance,with apin to fit into the spiral groove of thetube, and is moved by a thumb-piece sliding on the top of the tube, witha pin connecting with the tweezers, as represented by Fig. 3.

The clasp may be held together by any suitable device, such as a screw,spring, or by a latch, as represented by Fig. 4.. Fig. 5 is thetraversing plate, which moves in grooves made in the plate of the claspand carries the tweezers to the working-point in the operation of makingthe button-hole.

Ido not confine myself to the use of the spiral groove inthe tube togive arotary motion to the tweezers, as that motion may be given bymaking a twist or screw to the tweezers; or they may be revolved by thethumb while in the act of moving the tweezers back and forthto catch thethread.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the sliding plate with the revolving tweezers,operating and arranged substantially in themannerand for the purposehereinbefore set forth.

OTIS AVERY.
